Description This command filters not only multicast data, but also the multicast data encapsulated
in register packet.
If source address filtering and basic ACL are configured, all the multicast data packets
received will be matched with source addresses. The packet which does not pass the
matching will be discarded.
If source address filtering and advanced ACL are configured, all the multicast data
packets received will be matched with source and group addresses. The packet which
does not pass the matching will be discarded.
If this command is executed repeatedly, the new configuration will overwrite the
previous one.
